Volume of 1 metel cube = 6³ => 216 cm³
" " 2 " " = 8³ => 512 cm³
" " 3 " " = 10³ => 1000 cm³
Volume of whole cube = 216 + 512 + 1000
=>1728 cm³
surface area 1st cube = 6×6²= 216cm²
" " 2nd " = 6×8² = 384cm²
" " 3rd " = 6×10² = 600 cm²
Surface area of whole cube = 216+384+600
=> 1200cm²
" " 2 " " = 8³ => 512 cm³
" " 3 " " = 10³ => 1000 cm³
Volume of whole cube = 216 + 512 + 1000
=>1728 cm³
surface area 1st cube = 6×6²= 216cm²
" " 2nd " = 6×8² = 384cm²
" " 3rd " = 6×10² = 600 cm²
Surface area of whole cube = 216+384+600
=> 1200cm²
